Has anyone built an Aquarium Controller using the Reef-Pi Platform? It runs on a Raspberry Pi and seems to be modular and quite powerful. Also, unlike some other similar DIY projects I have seen on the net, this seems to be well supported and currently updated.

I need to replace a TC420 LED controller and am thinking this might be a better idea in the long term. It has the ability to control lights, dosing, wavemakers, ATU, temperature etc, etc.

Does anyone here use a W1209 temp controller?
Input is 12v nd output is 220v for a heater specifically...what's the best way to wire it without cutting the plug off the heater.
Any help/ suggestions appreciated.]]>8Dastaco controller for carxSun, 04 Nov 2018 22:11:50 +0000https://www.marineaquariumsa.com/threads/dastaco-controller-for-carx.74120/

just dial in the desired alk level and the rest is automated.

keep to see at what price tag they'd come in at.

The DaStaCo reactor is a state of the art fully automated Calcium and Alkalinity Reactor for SPS dominant reef aquariums where a consistent, heavy and reliable supply of minerals are needed. Once operational, all that is required to deliver more or less alkalinity is the simple turn of one dial...

https://www.marineaquariumsa.com/threads/saga-orp-probe.80027/invalid@example.com (RiaanP)RiaanPNeed to replace mine. But got quoted R2000 for just the probe. I struggle to justify that amount but as I'm going to use a much bigger ozone unit than the norm, I am forced to have a reliable probe. I can understand why guys rather run their ozone on simple timers. Far cheaper.

I really like the Skimz one but can't get it locally and I already have stuff sat with customs for over a month so not keen to import!!

https://www.marineaquariumsa.com/threads/your-opinions-on-test-kits.76229/invalid@example.com (Corne)CorneHi
Some advice to a newbie , please.
I have the option of a Serra test kit at R2,200 which tests for: PH, KH, NH4, NO3, NO2, O2, CU, CA, MG, SiO2, PO4.
Or alternatively I could buy the Red Sea brand test kits seperately. For R2,200 i would be able to buy enough separate kits to test for all of the above except O2 & SiO2
Which would you go for?

I would like 160cm x 60cm x 60 cm. I have used the glass Calculator and it recons that I use 12mm for sides and 16 mm for the base! But, due to cost. I am thinking 8mm sides and 12mm base. This gives me a safety factor of 2.1 (sides) and 2.7 (Base), not the 3.8!

My Question is this: I currently have a standard 4 foot (120cm x 45cm x 45cm) 6mm sides and 8mm...

In using it I found it to be quite unreliable in some aspects and do not recommend using the coke bottle method as the coke bottles we have are different to the ones we have in SA. But all the calculation and information is spot on. So I post this method which I have tweaked using Randy's calculations and found to be very reliable. Read through the article if you wish to get a better understanding of...

My father has given me an Aqua Mate DSG 3in1 SG Salinity and temperature meter
Granted it was bought a few years back, it's never been used and brand new. Any reviews, has anyone used one before? Also it says in the manual when I want to calibrate it I need to use the 30ppt solution they include- being a few years old it's all evaporated.. .how would I do it now?

Thanks!]]>0Does Kalkwasser destroys plastic bottles and containers?Fri, 09 Mar 2018 13:47:37 +0000https://www.marineaquariumsa.com/threads/does-kalkwasser-destroys-plastic-bottles-and-containers.76778/

I have been filling 12 2L Coke bottles with Kalwasser and RO to fill my ATO system. I recently found that the bottom of one bottle was cracked but put it down as just a broken bottle. Today I noticed that most of the bottles are cracked at the bottom and very brittle. Now I am worried about the plastic container that holds 20L for my ATO pump. Has...
